- the invention relates to a deflection adjustment roller a circumferential roller shell, the roller shell axially penetrating yoke and several in the axial direction of the roller by far hydrostatic and / or hydrodynamic support elements through which the Roller jacket on the yoke, forming an intermediate one Fluid cushion is supported, wherein a liquid discharge device is provided to operating fluid, in particular Lubricant that accumulates inside the roller during operation and a fluid ring flowing around the support elements
- the inner circumference of the roll shell forms from the inside of the roll to remove.
- DE 38 15 462 C shows a further deflection adjustment roller of the type mentioned above, on both sides of the support elements rectangular web parts are provided, the side of the respective support element in the direction of an adjacent support element protrude and that formed between the support elements Narrow flow channels.
- the object of the invention is a deflection adjusting roller to create the type mentioned in the simple and reliable way the inside of the roller The amount of fluid and the associated splashing power losses be reduced to a minimum can.
- the support elements and act provided fluid stripping elements targeted to that of Rolled jacket taken and flowing around the support elements Fluid, with the strippable by the fluid stripping elements Oil quantity is optimized so that the contained inside the roller Fluid quantity reduced to a minimum and thus the sufficient fluid film layers formed on the inner surface of the roll can be kept thin and accordingly the The splashing power losses occurring around the support elements are low.
- the fluid wiping elements arranged at least in part and / or trained to use only the Deflection adjustment roller are effective as the bottom roller, i.e. if the support elements and thus the fluid wiping elements in the top half of the roller while in use the deflection adjustment roller as the top roller, i.e. if the support elements and thus the fluid wiping element in the oil sump forming on the roller bottom are ineffective stay.
- the support elements are simply rounded trained and protrude preferably blade-shaped trained fluid wiping elements each approximately radially from the support elements, each in the flowing around the fluid ring facing the front area Support elements lie and opposed to the fluid ring are, if they are effective, and in each case in the flowing around fluid ring facing away from the rear Support elements lie and in the direction of flow of the fluid are directed if they are ineffective.
- the tips of the fluid wiping elements can advantageously with the respective support element by one about horizontal web to be connected to the flow resistance of the fluid wipers to decrease when they are ineffective.
- the webs expediently extend each from the tips of the fluid wiping elements to the area of the parallel to the roll axis Central axis of the support elements.
- two fluid wiping elements on opposite sides and especially symmetrical to the central axis of the respective support element are formed.
- the axial one Length of the scraper elements greater than the distance between the support members, thereby creating the discrete fluid rings that after leaving the formed between the support elements Flow channels become a little wider over their full To be able to remove the width from the roll shell.
- the scraper elements can also be active when the fluid wiping elements are effective to include those between the effective ones Fluid wiping elements still flowing narrow Wipe off fluid rings from the inner circumference of the roller shell.
- Fluid wiping elements and / or the scraper elements at least a fluid intake for a gravity assisted Fluid discharge assigned. This can be a relatively expensive process There is no fluid suction.
- the fluid wiping elements and / or the scraper elements at least one air baffle upstream be, which forms a gap with the roller shell, which is dimensioned in this way is that operating fluid entrained by the roller jacket passes through, but little boundary layer air that is within of the operating fluid is entrained by the roller jacket. This ensures that the fluid wiping elements or the scraped off fluid calmly can flow away and not through the entrained by the roller jacket Air is swirled. This is already achieved when the gap is only a few mm high.
- Figure 1 shows a schematic cross-sectional view Deflection adjusting roller according to the present invention.
- This comprises a circumferential roller shell 1, the roller shell 1 axially penetrating yoke 2 and several in the axial direction the roller is arranged next to each other at a distance a hydrostatic and / or hydrodynamic support elements 3, through the roll shell 1 on the yoke 2 under training an intermediate fluid cushion supported and under Formation of a press nip can be pressed radially against a counter roller 22 is.
- the support elements 3 are each piston-shaped and sealingly used in pressure chambers 10 which in the yoke 2 are formed and with a supply line 11 Pressurized fluid are supplied to the support elements 3 against the To press the inner surface of the roll shell 1.
- the support elements 3 each have a roll shell side Sliding surface 14 formed in the hydraulic pressure pockets 12 are connected to the respective pressure chamber via lines 13 10 are connected and fed by this.
- FIG. 3 and 4 are round Outer periphery of the support elements 3 each have two fluid wiping elements 4 symmetrical to the transverse to the roller axis X Center axis of the respective support element 3 is formed.
- the fluid wiping elements 4 each project laterally from the Support elements 3 and extend into between the adjacent support elements 3 flow channels formed into the flow channels in a targeted manner Support elements 3 flowing operating fluid from the inner surface to strip the roll shell 1.
- the fluid wiping elements 4 are designed such that they only in one rotation of the roll shell 1 Are effective while being in the opposite direction Direction of the rotating roller jacket 1 essentially remain ineffective.
- the fluid wiping elements 4 are designed in the shape of a blade and each project approximately radially from the support elements 3 from where they each face the fluid flow F. front area of the support elements 3 and the Roll jacket 1 entrained fluid flow F opposite are, if they are effective, as indicated in Figure 3 is.
- the fluid wiping elements 4th each in the rear facing away from the flowing fluid F. Area of the support elements 3 and are in the direction of flow of the fluid F directed, as shown in Figure 4, so that they offer low flow resistance and therefore are ineffective.
- the tips of the fluid wiping elements with the support element 3 by one approximately in the flow direction extending reinforcing web 23 connected by the Point of the fluid wiping element 4 starting approximately tangentially connects to the circumference of the support element 3.
- the fluid wiping elements 4 the fluid entrained by the roller jacket 1 F opposed and therefore effective, so that the support elements 3 flowing fluid F from the inner surface of the Roll shell 1 is scraped off.
- the stripped fluid F is in a fluid holder attached to the side of the yoke 2 7 collected and via a discharge line 8 and a central Discharge line 9 led out of the roller.
- the axial length l is that of the support elements 3 by half a pitch T of the support element arrangement offset scraper elements 5 in the present case somewhat larger than the distance a between the support elements 3 to the discrete fluid rings that after leaving the between the channels 3 formed channels become somewhat wider, decrease over its full width from the roll shell 1 can.
- the scraper elements 5 are like the fluid wiping elements 4 formed such that they only in one direction of rotation Roll shell 1 are effective, namely when the to Support elements 3 provided fluid wiping elements 4 ineffective are then in place of the fluid wiping elements 4 between the support elements 3 on the inner surface of the roll shell Strip the fluid rings formed from the roller jacket 1 to be able to.
- the scraper element 5 by spring force against the inner surface of the roll shell 1 pressed.
- the blade is designed Scraper element 5 preferably about a perpendicular to the roller axis X.
- Axis B pivotally attached to a plunger 15, the in a receptacle 16 provided in the yoke 2 radially to Roll sleeve is slidably guided.
- a compression spring 6 is inserted through which the scraper element 2 pressed against the inner surface of the roll shell 1 becomes.
- the scraper elements 5 are each with one of the inner surface of the roll shell 1 facing inclined surface 17, through which between the inner circumference of the roll shell 1 and the respective scraper element 5 held against it a wedge gap results. So that the scraper elements 5 are only effective with roller jacket 1 rotating in a direction R, while facing you in the opposite direction rotating roller shell 1 due to the caused by the wedge gap let fluid flow through hydrodynamic effect.
- the fluid wiping elements 4 are ineffective and extend from that facing away from the fluid Back of the support elements 3 approximately in the flow direction, see above that hardly any fluid is stripped from the roll shell 1 by them and it is only used for channeling the between the Support elements 3 flowing fluid serve as in Figure 4 is shown.
- the Scraper elements 5 in their effective position to the between the support elements 3 channeled fluid rings from To strip off roller jacket 1.
- a fluid intake 7 is also assigned to the scraper elements 5, which collects the stripped fluid.
- the fluid intake 7 is via a discharge line opening into the bottom thereof 8 with the central discharge line provided in yoke 2 9 connected, which is lower than the fluid intake 7, so that the fluid is due solely to the hydrostatic pressure or gravity can drain. Suction is in usually not required.
- each air baffle 20 which each form a gap with the roll shell 1
- the distance between Air baffle 20 and inner circumference of the roll shell 1 is preferably less than 5 mm.
- Fluid intake 7 also between two at the top of the Yokes 2 provided strips 21 formed to fluid from the fluid wiping elements provided on the top of the yoke 2 4 or scraper elements 5 is stripped to collect.
